“[YouTube Red] gives our film an exciting opportunity to connect with a huge audience of digitally native fans eager to see their favorite performers in high-end content in a proven genre,” Legendary Digital Senior Vice President Greg Siegel said in a statement.

The first feature length thriller to be released on YouTube Red, “The Thinning” centers on two students (Paul and List) in a world where an aptitude test is used for population control. The students discover the test is a cover up for a conspiracy and attempt to uncover the truth.

Gallagher wrote the screenplay with his “Internet Famous” co-writer Steve Greene. The pair and producer Jana Winternintz won Legendary’s House of Horrors short film contest, launched in partnership with YouTube Spaces to find emerging talent.
